PHASE EQUILIBRIUMS IN THE SYSTEM Tl?TlCl?S

The phase equilibriums in the system Tl?S?Cl in the field of structures of Tl-TlCl-S was investigated using the DTA method and XRF method. In this research work, the polymeric section TlCl?S, Тl?Tl6SCl4. Tl2S??T2Cl?, Tl2S??TlSCl?, the isothermal section by 300K and the projection of a liquidus surface of Tl-TlCl-S system were schemed. The fields of primary crystallization of five phases, including the only threefold connection of Tl6SCl4 are contoured, types and coordinates non- and monovariant equilibriums are defined. The author shows the existence in the Tl-TlCl-S system of four liquid phases: based on metal thallium (L1), TlCl (L2), thallium sulphochloride and sulphides (L3) and sulfur (L4). The interaction of these mutually saturated liquors leads to formation of two threefold (L1+L2+L3 and L2+L3+L4) and five double fields of aliquation. The solubility based on firm phases is insignificant.
